The magnets for the SESAME storage ring need to be magnetically measured to evaluate the prototype magnets and compare their characteristics with the design parameters. WP4 organizes and supervises these magnetic measurements. Equipment capable of handling the measurement of the prototype magnets will be setup at CERN and then sent to SESAME for the series measurements. Training of SESAME scientists will be given at CERN during the construction phase in order to develop a measuring laboratory at SESAME. Then, the 1st combined function bending magnet of the storage ring will be measured at CERN and re-measured at ALBA-CELLS to verify consistency between CERN and ALBA-CELLS results. Finally, the power test, hydraulic tests and the magnetic measurement of the series bending magnets will be subcontracted to ALBA-CELLS.
